Ports tree frozen in preparation for 7.2-RELEASE

No commits will be allowed without explicit portmgr approval. We hope we can keep the freeze short and go into slush after two weeks. The tree will be completely unfrozen after the release is announced. For the full schedule, see the release schedule.

As always, only commit that fix existing breakage will be allowed during the freeze and we encourage everyone will help fix as many ports as possible for this release. For more information about what kinds of commits are allowed during which period, please see the portmgr policies webpage.
